Analyte Monitoring Device and Methods of Use - An analyte monitor includes a sensor, a sensor control unit, and a display unit. The sensor has, for example, a substrate, a recessed channel formed in the substrate, and conductive material disposed in the recessed channel to form a working electrode. The sensor control unit typically has a housing adapted for placement on skin and is adapted to receive a portion of an electrochemical sensor. The sensor control unit also includes two or more conductive contacts disposed on the housing and configured for coupling to two or more contact pads on the sensor. A transmitter is disposed in the housing and coupled to the plurality of conductive contacts for transmitting data obtained using the sensor. The display unit has a receiver for receiving data transmitted by the transmitter of the sensor control unit and a display coupled to the receiver for displaying an indication of a level of an analyte. The analyte monitor may also be part of a drug delivery system to alter the level of the analyte based on the data obtained using the sensor.

INTEGRATED MINIATURIZED FIBER OPTIC PROBE - A fiber optic probe having one or more photodetectors bound thereto is provided. By directly integrating thin, flexible photodetectors with an optical fiber, the probes provide a compact structure that increases throughput and decreases cost, making it practical for a clinical use. In some embodiments, the fiber optic probes are small enough for insertion into the shaft of a needle, such as a biopsy needle.

METHODS AND SYSTEMS FOR EXCHANGING SIGNALS WITH MEDICAL OR PHYSIOLOGICAL INSTRUMENTATION - A process is described for testing a biomedical property of an internal tissue of a patient. Optical energy emitted by an external source is transferred through a nail of the patient to an instrument device implanted beneath the nail. A portion of the transferred optical energy is converted to electrical power for driving components of the implanted instrument. Using the electrical power, a characteristic of the internal tissue associated with the measurement of the biomedical property is sensed and an optical signal based on the sensed characteristic is transmitted through the nail to an external data reader.

INJECTION DEVICE - An injection device for use with tissue of a mammalian body comprising a first tubular member and a second tubular member slidably disposed in the first tubular member. The first and second tubular members have respective proximal and distal extremities. The distal extremity of the second tubular member is provided with a needle that is extendable from the distal extremity of the first tubular member. The proximal extremity of the second tubular member is lockable relative to the proximal extremity of the first tubular member. The second tubular member has a column strength when locked within the first tubular member for limiting retraction of the second tubular member relative to the first tubular member during puncture of the tissue by the needle.

Fiber-optic probe - In a fiber-optic probe for intravascular measurements, e.g. oxygen saturation measurements, the fiber-optical core has only two fibers. A single fiber core is also possible. A reinforcement fiber improves stiffness, kink resistance and overall strength of the probe. The reinforcement fiber is arranged essentially parallel to the core fibers. The reinforcement fiber may also be wound around the core in a helical manner thus improving the mechanical properties to an even higher degree. The outside of the sheath is coated with an antithrombogenic coating for reducing the danger of clots forming at the surface. The reinforcement fiber may be made of carbon, metal, ceramics or aramide.

Methods and Reagents for in Vivo Imaging of Cancel Cell Lines - Provided is reagents and methods for non-invasive in vivo imaging wherein the reagents comprise targeted carrier molecules conjugated to a NIB reporter molecule. In one aspect the targeted carrier molecule is an antibody, or fragment thereof that has specificity for an antigen in a living body, animal or human. In one embodiment the antibodes are anti-cancer/tumor marker antibodies, organ specific antibodies, tissue specific antibodies, cell type specific antibodies, cell surface specific antibodies, anti-viral antibodies, anti-bacterial antibodies and anti-pathogenic antibodies. The NIP reporter molecules are any fluorescent reporter molecule compatible with in vivo imaging and generally having an excitation wavelength of at least 580 nm.

Controlling Transfer of Objects Affecting Optical Characteristics - An implantable product such as an article, device, or system can include analyte and non-analyte containers in parts that can be operated as optical cavities. The product can also include fluidic components such as filter assemblies that control transfer of objects that affect or shift spectrum features or characteristics such as by shifting transmission mode peaks or reflection mode valleys, shifting phase, reducing maxima or contrast, or increasing intermediate intensity width such as full width half maximum (FWHM). Analyte, e.g. glucose molecules, can be predominantly included in a set of objects that transfer more rapidly into the analyte container than other objects, and can have a negligible or zero rate of transfer into the non-analyte container; objects that transfer more rapidly into the non-analyte container can include objects smaller than the analyte or molecules of a set of selected types, including, e.g., sodium chloride. Output light from the containers accordingly includes information about analyte.
